Glass reinforced concrete (GRC)

Glass fiber reinforced concrete (GRC, GFRC) is a lightweight, strong, and reliable finishing material that successfully replaces natural stone. Thanks to its plasticity, GFRC elements can have practically any shape and size, and the wide range of textures and colors opens up limitless possibilities for design.

The unique properties of glass fiber reinforced concrete are determined by its high strength. External loads are absorbed by the elastic fiberglass that reinforces the fine-grained concrete. It increases resistance to bending and stretching many times over, and the impact strength of the composite increases 10–15 times compared to ordinary reinforced concrete.

Advantages of SFB: Durability: the material easily withstands temperature fluctuations, humidity, and the action of chemical reagents. Longevity and safety: SFB is completely non-combustible. Decorative elements made from it last just as long as the load-bearing structure of the building. Cost-effectiveness: the low weight of the products reduces transportation and installation costs. Protection: the material is almost impermeable to chlorides, reliably protecting steel reinforcement from corrosion. It is waterproof, crack-resistant, and withstands more than 500 freeze-thaw cycles. Aesthetics and texture imitation: Concrete is a brutal material that is ideal for interiors in minimalist, hi-tech, techno, and loft styles. Although ordinary reinforced concrete is cheap, its use is limited by its large weight and the vulnerability of its reinforcement to corrosion.

Glass fiber reinforced concrete is a composition based on concrete filled with chopped glass fiber (monofilament). Unlike ordinary concrete, which often cracks along the boundaries of the filler grains (sand or gravel), GFRC contains randomly arranged long fibers. They are homogeneously mixed in the mass and increase tensile and compressive strength by tens of times.

The material can be excellently colored both throughout the mass (by adding pigment to the mixture) and on the surface.

Compared to ordinary concrete, glass fiber reinforced concrete has the following advantages:

Lightweight structures.
High tensile, compressive, and bending strength.
Tensile strength is 5 times higher.
Impact strength is 15 times higher.
Increased frost resistance (over 300–500 cycles).
